Ehhh Weird!
I really start believing that it's either the directory you use in
$somevar that's wrong, or that the permissions are wrong. I have no
troubles wse with the constructions.
It doesn't matter if I only type the path, or that I put the whole
path in one variable or that I use both a variable and a (part of)
the path. The result is exactly the same. (as it should btw).

Renze,
I found that it works if I pass only a variable or a path in, not both.
e.g.opendir("/path/to/foo") works
opendir("$variable") where variable contains "path/to/foo" also works
opendir("$somevar/some/path") does NOT work.
go figure.
cheers,
jaxon

RE: [PHP] RE: help, weird include problem with functions
yes, I'm sure the directory exists :)
here is the actual code, I suppose this would have been more helpful to
start:
http://localhost/modules in a
settings file
echo "$modroot from included"; //this echos "http://localhost/modules";
properly
//the below throws the error, OpenDir: No such file or directory (error 2)
in (this function file name)
//but I can replce the $modroot/common with a hard-coded path and it works
fine.
$handle=opendir("$modroot/common");
while ($file = readdir($handle))
{ //load files in $directory into array
if ($file != ".." && $file != ".")
{
$files_to_include[count($files_to_include)] = $file;
}
}
//clean up and sort
closedir($handle);
if (is_array($files_to_include))
{
while (list ($key, $val) = each ($files_to_include))
{
include "$modroot/common/$val";
}
}
}
incl_common();
?>

Are you sure the directory you try to open actualy exists?
Btw... for things like this you better use:
if (!($handle = opendir ("$bar/common/"))) {
// Some error here, and don't try to use $handle after this!
}

hmm...yes, it does work, I jumped the gun on the simple example, cuz I thought it was an echo problem.. my un-simplified example has an opendir() in function foo() file. function.php is: so the simple example does indeed work, but the opendir() is choking trying to deal with the variable. hmmm... jaxon > -Original Message- > From: Renze Munnik [mailto:[EMAIL PROTECTED]] > Sent: Thursday, August 09, 2001 1:06 PM > To: [EMAIL PROTECTED]; [EMAIL PROTECTED] > Subject: Re: [PHP] RE: help, weird include problem with functions > > > On Thu, Aug 09, 2001 at 12:48:38PM -0400, Jaxon wrote: > > oh, this still happens when I fix the missing () in the foo > declaration :) > > > > cheers, > > jaxon > > > > > Works fine, no problems at all! > > > -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]

Are you sure function.php is included at all? Because if the only problem would be $bar, the output would at least be: someval from page.php from foo Like I said... I don't have any problems with it. The output is: someval from page.php someval from foo (and all this without any errors or warnings!)

You need to include settings.php in functions.php.
